ALFALFA-CULTIVA'IOR.

To all whom it may concern:

Be it known that I, CHARLEs RoszMAN, a citizen of the United States, residing at Cecil, in the county of Paulding and State of Ohio, have invented certain new and useful Improvements in Alfalfa-Cultivators, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to alfalfa cultivators.

The object of the invention is to provide a machine of this character which shall be simple in construction, thoroughly eflicient and durable in use, and in which the parts may be adjusted so as to vary the cut as requisite.

lVith the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of an alfalfa cultivator, as will be hereinafter described and claimed.

In the accompanying drawing, forming a part of this specification, and in which like characters of reference designate corresponding parts: Figure 1 is a top plan view of the apparatus; Fig. 2 is a side elevation; Fig. 3 is an inverted view of the beam showing the plow share or cutter connected therewith; and Fig. 4 is a perspective detail view of a modified form'of beam.

In the drawing, the frame of the machine is shown as composed of a plurality of longitudinal bars 1, 2, 3 and 4, which are connected by end and intermediate braces 5 and 6 respectively, the frame as a whole being of rectangular contour and of skeleton construction. Secured on each side of the frame is a bar 7, and in these two bars is secured a shaft 8 carrying ordinary ground wheels 9. At the rear end of the frame is arranged a beam 10 carrying on its under side a plurality of shares or knives 11, 12, 13 and 14:, these latter being detachably connected with the beam by hangers or brackets 15. The two center knives 12 and 13 constitute a V, the knife 12 projecting beyond the knife 13, while the knives 11 and 14 are arranged in parallelism with the knives 12 and 13, the object of the knives 11 and 14 being to impart an even draw to the machine. The upper side of the beam carries a plurality of standards 16, three in this instance being shown, through which passes a shaft 17, the ends of which are bent at Specification of Letters Patent.

Patented Apr. 13, 1915.

Application filed: April 1, 1914. Serial No. 828,872:

right angles to the length and pivotally connected with a shaft 18 extending through the longitudinal. frame bars.

In order to regulate the cut of the plow, an adjusting mechanism for the purpose is employed which comprises an ordinary locking lever 19 which is pivoted to one of the side bars adjacent its rear end, and provided with the latch 20 to engage with the rack bar 2].. The lever is connected with one end of a rod 22, the other end of which is connected with the shaft 17, and by this arrangement it will be seen that the beam may lifted on a crest as requisite. Arranged intermediate of the ends of the frame and projecting through all of the longitudinal frame bars is a shaft 23 carrying a plurality of hangers 24: that are connected by braces 25, the lower end of each hanger being provided with a plurality of orifices 26 that are designed to be engaged by a rod 27 and pivotally connected with the rod ends are a series of bars 28 the outer ends of which are rigidly connected with the beam. By this manner of connecting the beam with the hangers, the former will be arranged for swinging move ment to permit adjustment of the plows, as above referred to.

Pivotally mounted upon the rod 27 are a series of bars 29, 30, 31, 32 and 33, the bars 29 and 33 being disposed at inward converging angles relative to each other, the outer ends of all the bars being connected to constitute a draw bar to which the clevis may be connected to draw the machine over the ground, the outer end of the draw bar being projected through a guide 31 depending from the front end of the bar.

In order to brace the structure as a whole, and vto transmit the draft directly to the beam, rods 35 are employed, one end of each of which is secured to one of the plow brackets, and the other end being provided with an eye or keeper to engage the rod 27.

Secured to the under side of the beam, adj acent each end thereof, is a rod 36, the outer ends of the rod being connected, forming thereby a V-shaped draw bar, the intermediate portions of the rods being hinged together, in order to permit the outer ends thereof to spring freely.

Where the work to be done is light in character, the form of plow shown in Fig. 1 may be employed, this being provided with three knives 37. The beam 38 to which the plow is connected will be provided with 7 arms 39 which will be slipped around the beam and be bolted thereto, or, if preferred,

the beam may remain in position and the r shares be secured thereto in the usual or any V alfalfa cultivator.

Having thus deseribedmy invention, what I claim is:

- 1. An apparatus ofthe class described including a frame, a beam, a plurality of shares detachably secured thereto, a plu- 'rality of parallel bars securedat'their outer ends to the beam, hanger arms pivotally connected to the frame and provided with a plurality of alined openings, the inner ends of the bars being pivotally connected in one of the openings in the hanger arms, and means connected with the beam to raise and lower the same.

2. An apparatus of the class described including a frame, a beam, a plurality of shares carried thereby, the center shares being arranged to form a V and one share proj ecting beyond the other, the remaining shares being arranged in parallel relation to the center shares, a plurality of parallel bars secured'at their outer ends to the beam, hanger arms pivotally connected to the frame, the inner ends of the bars being pivotally connected to the hanger arms, and means coimected with the beam to raise and lower the same.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.

CHARLES ROSZMAN.
